The answer to this riddle is 27, further confirming a count down to June 2.

It also appears that Boon is teasing another Injustice: Gods Among Us title when he asked what special moves would people like to see Power Girl from the DC comics have. Interestingly enough, Boon replied to a rather bummed out Injustice fan about Power Girl not being included as a playable character in the first title, saying:

RT @RAWFShowtime@noobde Rub it in Ed. -_- Still bummed she didn’t make it into the game to begin with… EB: In THIS version! 😉 — Ed Boon (@noobde) May 6, 2014

In addition, when Boon was asked whether or not he would announce a new Mortal Kombat title or Injustice on June 2, he simply replied, “No, no…Injustice Too!”

Considering Ed Boon’s reputation to “troll” Mortal Kombat fans, you should take the last bit with a grain of salt. However, a DC rep revealed earlier that a new Injustice game will be released in the future.
